The Wheel of Time and Space moves forward two squares, and this is the fifth cycle, and the time is noon.

As soon as the bell rang for the end of class, the classmates walked out of the classroom one after another, and for a while there was a lot of noise, Wen Cheng woke up from his slumber, licked his dry lips, and found that Liu Zhen sighed sadly towards the window, his fingers wrapped around the long hair that fell on his shoulders.

Liu Zhen's seat was next to the windowsill, and the only way to go out was to ask Wen Cheng to get out of the way, according to the usual style, she would cough sharply twice, and the boy would stand up stupidly, there is no doubt that such a scene of patiently waiting for Wen Cheng to wake up is extremely rare.

"Ah......h

The blackboard at the front of the classroom reads "Countdown to 99 days."

"Didn't you sleep well?" Wen Cheng patted Liu Zhen on the shoulder.

"No," Liu Zhen replied without replying, "Can you let it go, I'm going to the unfinished building."

Wen Cheng stood up and looked at Yoo Jin, who was about to leave, with worried eyes.

"Liu Zhen," Su Meng tugged at the cuffs of her sweater, "Let's go to the cafeteria for lunch together, wouldn't we be able to go back after eating?"

"Don't eat with this idiot." Liu Zhen crossed his arms and glanced at Wen Cheng and said.

Su Meng and Wen Cheng were silent, and Liu Zhen quietly lowered the corners of his mouth.

"It's okay, you two eat, I'm not very hungry, but my neck is a little sore, just lie here for a while." Wen Cheng touched his neck and smiled.

After ten seconds of silence, Liu Zhen suddenly turned his head and looked at Su Meng with panicked eyes, and Su Meng nodded with serious eyes.

"Sore neck?" Liu Zhen then asked Wen Cheng.

"yes." Wen Cheng.

"Tell me, where's the location?" Liu Zhen approached and asked.

"The back of the neck," Wen Cheng pinched the back of his neck, "Maybe I stayed up too late last night."

Liu Zhen breathed a sigh of relief and glanced at Wen Cheng, "It's the same......

After a while, she waved her hand, "Forget it, let's eat together." Glancing at Wen Cheng quietly, she continued, "I just want to discuss something with you, and talk while eating."

After saying this, Liu Zhenjing threw his hair and hurriedly left the classroom, leaving Wen Cheng and Su Meng far behind.

The two of them followed the red back unhurriedly, strolling along the long corridor leading to the cafeteria in the teaching building, surrounded by a field of early spring greenery, the weather was not cold, and the sun shone warm on the shoulders.

"That's right, Su Meng." As he walked down the road, he asked, "Why did Liu Zhen react so strangely when my neck was sore just now?"

"Hmm......" Su Meng pursed her lips and pushed her hair behind her ears, "Are you sure you want to know?"

"Sure." Wen Cheng nodded.

"Actually, we're in a space-time loop...... Let me think about how to explain it......" Su Meng put her hands together in front of her skirt to sort out the words.

"No wonder!" Wen Cheng interrupted her and said, "Su Meng, do you know, I always feel that this scene is familiar, whether it is Liu Zhen sighing out of the window or me going to the cafeteria with you, this scene always feels very rare, and it always feels like it has happened."

"So you're aware of it...... That's easy," his blue eyes lit up, "I'll talk about your sore neck first, Wen Cheng, are you sure you have a sore neck or a sore neck?"

"Ah...... Hehe, it's actually quite painful." The boy touched the back of his neck and smiled bitterly.

"Hey," Su Meng stretched out his hand to help him rub the back of his neck, "This is a residual pain, presumably the cause of death last time."

"I see," Wen Cheng said, "but Su Meng, why are we in a space-time loop?"

"It's a large space-time spell," Su Meng raised her finger and whispered, she pointed to the sky again, "Wen Cheng, can you see a huge Möbius ring in the sky?"

"Mobius Ring?" Wen Cheng looked at the sky and shook his head.

"It's a hexagonal cross-sectional transparent Möbius ring, but it can capture the outline," Su Meng said, "Actually, Liu Zhen can't see it, I don't know why only I can see it, maybe it's because I studied space spells." She paused and said, "The preliminary estimate is that this loop should be in low earth orbit, which is exactly the size of the entire Qiantang City."

"You mean?!" Wen Cheng was shocked, "The entire Qiantang City is trapped in this space-time spell?"

"Yes," Su Meng tilted his head and smiled bitterly, "And such a huge space-time spell is undoubtedly driven by the earth's core magic source, and part of the frequency band of the nuclear source has already been occupied, even if Liu is really a great magician, he can't easily penetrate the nuclear source, otherwise there will be space-time disorder."

"Who released it? What the hell is he trying to do?" Wen Cheng pressed his fingers to his lips and pondered.

"With such a huge space-time spell, there is no doubt that only the great magician who penetrates the nuclear source can do it." Su Meng replied quickly.

"Could it be ......" Wen Cheng was shocked.

"It can't be Liu Zhen," Su Meng smiled bitterly, "She's been busy solving the problem of loops and mechanical dogs lately, not to mention that she doesn't know space-time spells."

"yes," he suddenly turned to Su Meng, "That's right, Su Meng."

"Well, you say."

"If it's a space-time loop, why is the memory of the last time blurry?"

"Hmm," Su Meng nodded, "The space-time spell transcends the time dimension, but there is no doubt that we are still on a one-dimensional timeline, so the last cycle can only recall what has already happened at the same point in time, and the memory of the last time is the most vivid."

"But......" Wen Cheng frowned, "What's the pain in my neck?" It should have happened after this point in time......

"Actually, this is the clue, just like a combination lock, although the number is cleared after you keep trying, there is no doubt that it leaves traces of friction and twisting, and the pain remains roughly like this." Su Meng put a warm little hand on the back of his neck, "This can deduce the possible reason for the defeat last time, and ah, you can also infer the intensity of the last battle through the residue of mana."

"Mana residue? …… I can understand that the plane has restarted, but the mana is undoubtedly consumed?" Wen Cheng asked as he nodded.

"That's right," Su Meng nodded with satisfaction, "Actually, there is another way to take the initiative to break the game, which is to set up anchor points."

"Anchor?" Wen Cheng was puzzled.

Su Meng pushed his glasses seriously, "As long as you encounter extremely rare things, you can set an anchor point, such as Liu Zhen sleeping on the table with you, this kind of thing has never happened, so the fifth anchor point I engraved on the table was triggered, and the function of the anchor point is to trigger alertness and judgment times, and guess what is about to happen based on the previous different memories." She continued, "Anchor points are usually engraved on objects, and at the moment they are carved and at the same point after that, the anchor point will trigger a bright light, and the other time the anchor point will glow as a dull crystal light as a mana wreckage."

Wen Cheng swallowed in a daze, and Su Meng added with a smile, "As her family crest, Liu Zhen's anchor point is a Tai Chi pattern that alternates between dark red and black, of course, only she can see it."

"Su Meng, where is your anchor point?"

"Wen Cheng, you also know...... I can't talk about a magical family......" Su Meng smiled bitterly, "So I don't have any family crests, but I don't know why, my anchor point is a pentagram."

"Wait, do I understand that the anchor point is not drawn by itself, but is a natural symbol?"

"That's right, the anchor point is actually bound to the gene, and because of this, only you can see it," Su Meng nodded, "Wen Cheng, the anchor program is a bit complicated, I want to teach you after you master the basic method."

"It's okay, I don't understand anything now, hehe."

"Wen Cheng, don't rush, take your time, now whether it's a mechanical dog or a loop, there is Liu Zhen in front of you, you just need to keep up slowly."

"Hmm!" Wen Cheng nodded.

Before they knew it, they had arrived at the door of the cafeteria, and the two found that Liu Zhen had occupied a seat early, and the food had been neatly arranged, showing a smile with unknown intentions.

"What's wrong with her......" Wen Cheng was stunned.

"Wen Cheng, that ......" Su Meng smiled bitterly, "Do you remember that Liu Zhen said that he had something to discuss with you......
